A British woman named Louise Neathway was arrested Wednesday and charged with harassing and extorting money from New York Yankees general manager Brian Cashman, the New York Daily News reports.

Neathway, 36, was arraigned in Manhattan Criminal Court on Thursday and remains in prison on $300,000 bond. She claims to have been Cashman’s mistress, though she has a history of stalking.

"The defendant extorted approximately $6,000 from the victim and attempted to extort over $15,000," prosecutor Eric Iverson said in court Thursday, according to the Daily News.

The defense painted Neathway in a much different light, however.

"This is a married man who has an inappropriate relationship with a single mom—it ended badly," said Stephen McCarthy, one of Neathway’s attorneys.

According to the Daily News, Cashman cooperated in a police dragnet that led to Neathway’s arrest. Cashman told police he met Neathway in April and that this past fall, he deposited $6000 into her bank accounts after she asked him for $15,000 for an unspecified medical treatment and threatened to go public if he declined to send her money.

Cashman told police Neathway made "multiple and harassing telephone calls" to him between Jan. 29 and 30, the Daily News reports.

Neathway was arrested for trespassing in North Carolina in 1998, has two open upstate warrants for harassment and is on probation in New Jersey in a stalking-related case, according to the Daily News.

The Yankees didn’t comment on the situation. A spokesman for Cashman said only that, "Brian is very grateful that this matter is being handled by law enforcement.”
